reported that it was possible to add new icons to the default set by altering the manifest.xml of the document. I am a bit puzzled because the pdf manifests do not show any reference to icons, so I hope we will have more info about this hack from the used that discovered it
Also, it has been reported by Herve that the manifestation processing (to build a folder with the original document plus a manifest) fails when the original filename is UPGRADE.txt. Funny but not random, I checked it. No idea about what happens for UPGRADE.pdf or UPGRADE.html.
